We scanned some face models(about 45) with different expressions to try to make personal blend shapes, and we wrap all of them as the tutorial to one neutral low-poly model we generated. However, when we wrapped our models, the details like acnes on the face are shaking after TransferTexture which we believe should be relatively fixed. What’s wrong when we wrapped the models? Should we select more points pairs near the details?
Hey! Sorry for the late reply!
Do you use the OpticalFlowWrapping node after the Wrapping/BlendWrapping node? The Wrapping/BlendWrapping nodes only rely on geometry. They can’t fit the mesh with pixel accuracy, that’s why you need to use the OpticalFlowWrapping node after that. Please let me know if this is the case.
If you do use the OpticalFlowWrapping node, you may need to tweak a few parameters like camera positions and camera resolutions.
